Thermoelectric energy conversion: Assessment of limiting capabilities

Physics of Complex Systems
Based on a thermodynamic ratio between the thermopower coefficient and entropy of the electrically conducting medium, we obtained an estimated value of the thermoelectric efficiency parameter ZT for an electronic system of fully ionised plasma.

Effect of interchain interaction on the electrical conductivity and thermopower of TTT2I3 crystals

Moldavian Journal of the Physical Sciences, 2013
Quasi one dimensional organic crystals of tetrathiotetracene-iodide TTT2I3 are promising materials for thermoelectric applications. A theoretical study of thermoelectric properties of these crystals was initially performed in terms of a one-dimensional ...

Pisarenko's Formula for the Thermopower [PDF]

arXiv
The thermopower $\alpha$ (also known as the Seebeck coefficient) is one of the most fundamental material characteristics for understanding charge carrier transport in thermoelectric materials. Here, we revisit the Pisarenko formula for the thermopower, which was traditionally considered valid only for non-degenerate semiconductors.
